3 Claims.

This invention relates to hinges and more particularly to so-calledloose pin hinges in which hinge straps having aligned knuckles are heldtogether by hinge pins extending longitudinally through the hollowknuckles.

Heretofore, in hinges of this type movement of the parts in use tendedto gradually work the pin out of position, producing an unsightlyappearance and ultimately permitting separation of the parts. Y

An object of this invention is to provide a hinge of the type set forthconstructed and arranged to resist any tendency to expel the hinge pinresulting from operation of the parts, while yet permitting quick andeasy assembling or disassembling thereof.

This and other objects which will be apparent to those skilled in theart areaccomplished by the present invention, one embodiment of which isillustrated in the accompanying drawing in which, Y

Fig; l is a View in elevation of a hinge assembly constructedinaccordance with one embodiment of my invention;

Fig. 2 is a transverse sectional view on the line 2-2 of Fig. 1 showingthe parts in locked position; and

Fig. 3 is a similar view showing the parts in position to permitseparation thereof.

The particular embodiment of this invention which has been chosen forthe purposes of illustration comprises a hinge having straps 5 and 6,the strap 5 having spaced hollow knuckles 'I and 8 and the strap 5having a centrally located hollow knuckle 9 adapted to be locatedbetween the knuckles 1 and 8. It will, of course, be understood that thepresent invention is equally adaptable to hinges having any desiredarrangement or number of knuckles.

In the present invention, the hinge pin is constructed and arranged toresist any tendency to work out of operative position, and provision ismade for preventing complete removal of the pin from the associatedparts without, however, preventing intentional separation of the hingeAs illustrated, the pin is sectional. Each'section is separately mountedin one of the hinge knuckles and means is provided for limiting thelongitudinal movement of each section and preventing removal thereoffrom the associated knuckle.

In the illustrated embodiment, theV pin section l0 is located in theupper knuckle 'l of the strap 5. It may or may not have an ornamentalhead Il. A stud I2 extends through the side wall of vlarly held in placeby a stud through the wall of the knuckle the knuckle and projects intoa key slot, groove, or the like I3 so as to permit limited longitudinalmovement of the pin section Ill while preventing removal thereof fromthe knuckle.

An intermediate pin section lll is mounted in 5 the knuckle 9 of thehingestrap 6 and a stud I5 or the like extending through the side wallof the knuckle engages a key slot I6 to permit limited longitudinalmovement of the pin in the knuckle.

A bottom pin section I1 is similarly located inV 10 the lower knuckle 3of the strap 5, and is simi- VI8 extending Y and projecting into a keyslot or groove I9 in the pin section.

Assuming that the pin sections have been 15 assembled in differentknuckles, the separate hinge straps 5 and 6 are connected by positioningeach pin section so that its lower end is withdrawn within theassociated knuckle. The pin section IG, which is located in theintermediate knuckle 9, is of such length as to be capable of beinglocated entirely within the knuckle. The top pin section IB is raised soas to withdraw its lower projecting end to within the knuckle 1,whereupon the hinge straps 5 and 6 can be positioned with the knucklesin alignment. Driving the upper pin section I0 downwardly projects itslower end into the adjacent knuckle 49, and in turn drives the pinsection I4 in the intermediate knuckle 9 downwardly into the bore of theknuckle 8.V The lower end of the bottom pin section Il projectsdownwardly as shown in Fig. 2, so that the lower end is accessible.

When it is desired to detach the hinge straps 5 and 6, the projectingend of the lower pin 5 section II is driven upwardly. This raises the Ypin sections Ill and I!) to the positions shown in Fig. 3, permittingseparation of the hinge straps.

Although the slots I3, I6 and I9 may be of any desired form, they arepreferably in the form of key slots which permit longitudinal movementof the pin sections in the knuckles, while preventing any relativerotation so as to reduceany tendency of the pin sections to work out ofthe knuckles as a result of operation of the hinge.

Although I have described in specific detail the preferred embodiment ofmy invention, it will be apparent that the invention can be variouslymodified and adapted within the scope of the appended claims.

I claim:

1. The combination in a hinge of separate straps having alignedknuckles, a sectional hinge pin having a section of such length in each55 straps together, said pin sections being in abut-y ting relationship,and a projecting end on an end section for use in causing longitudinalmovement of each pin section relative to said knuckles.

3. A hinge, comprising two leaves, one formed with two spaced knucklesand the other with a single knuckle adapted to be aligned with saidspaced knuckles in the space between the same, and a pintle made inthree separate sections adapted to be placed in said knuckles inabutting positions, the section placed in said single knuckle and thesection placed in one of said spaced knuckles being of the same lengthas said knuckles, the section placed in the other of said spacedknuckles being of greater length than its knuckle so as to enable it toprotrude beyond the inner end of said knuckle when moved in onedirection to thereby displace the pintle section in said single knuckleto extend into the adjacent other knuckle of said spaced knuckles.
